DIE.

SPECIFICATION forming part of Letters Patent No. 242,654, dated June '7, 1881.

Application filed February 12, 1881. (ModeL) To all whom 2t may concern:

Be it known that I, IRVING A. KILMER, a

citizen of the United States, resident at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Dies 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, in which Figure 1' is a plan view of the device, the punch removed. Fig. 2 is a cross-section of the die and punch. 3 is a longitudinal section of the device, Figs. 4 and 5 are details.

This invention relates to dies for cutting out the heads for bale-ties.

The invention consists in a die for cutting out the head for the arrow-headed bale-tie, as hereinafter described.

1n the annexed drawings, A represents a bed-plate, on which is secured the die-seat B, having the dovetail recess 1), and the diamond shaped aperture b in the bottom thereof, this aperture continuing through the bed-plate A;

To one side of this aperture are the holes y.

C is a die formed in two pieces, 0 c, the upper, 0, seated in and secured to the lower, 0. In this die are two triangular-shaped openings, it, having the shape and size of the head to be struck out, their angles rounded, and the apex of one alongside of the base of the other, a partition, being left between the two openings. To one'side of these openings are the holes 2 This die is placed in the recess b, with holes 2 registering with holes y and the two openings a over the aperture 12, and is held in place by the block D and set-screws E.

Fastened to bed-plate A, to one side of the die-seat B, having the holes yy, is the feed bench and gage.

F is a plate bearin g against the edge of seat B. Rising from this plate is the flange G, whose end 9 is rabbeted below, at z, to fit over the bottom of die-seat B, and at the side, at

Plate F has an enlarged portion, f, and flange f, and in the rabbet formed by these the flange G is secured. At the outer edge, av, of this plate F is secured anotherflange, H, similar to flange G, there being the space or channel 11 which, by means of pivot-pin K, the table is hinged to the flanges G and H. At its other end, 9', or the end next the die-seat B, this table has a notch, 8, cut in the corner next the flange G, and back of this notch a dependent lug, r, having the slot r, perpendicular to the table.

L is a bolt passing through washer l, flange G, slot 1", and flange H. This bolt is threaded, and has thereon, just inside of lug r, the squareedged nut M. The bottom of this nut bears on a plate, a, in -a recess in the inner end of plate F.

p p are slots in flange f, through which pass screws P P, entering the bed-plate A.

On the upper face of die-scat B, at the side b at right angles to table I, is a groove, N. In this groove is placed a presser-bar, R,

slotted at r and held by pin S. The end t of this bar is forked and carries a vertical roller, S. The outer end of the stem 2 of this bar is threaded, and the stem is shouldered at 1 and passes through an arm, T, rising from bed-plate A. Against shoulder 3 there bears a washer, 0, and between this and arm T there is placed on stem 2 a spring, V. On this bar, outside of arm T, there is placed a regulating nut, W. The notch s in plate I allows the necessary play to the presser-bar B. to accommodate it for strips of different widths.

X is a plate secured by its edge 00' to the top of flange H, and extending over table I, leaving a space, a, between. This plate X falls short of flange G, leaving an interval, as shown. On the edge 00 of plate X are formed two lugs, N.

Y is a strip having slotted ears 0 Through these slots pass screws p by-which this strip is adj ustably held to the lugs b The operation is as follows; The die is put in place and blocked to position, the apertures and holes registering. A cover-plate,Z, having holes 2 and triangular apertures 01, is placed on and secured to the die'seat B. The

drop A, having removably connected to its bottom 6 the triangular punches It and the pins is arranged so that as it falls its punches and pins will enter the corresponding openings below in the cover-plate and die. The horizontal position of the feed-bench is regulated bypins PPpassingthrough slots 19 p The strip of metal from which the heads are to be cut is fed along table I, the roller S, held up by spring V, keeping it true and easing the friction. As the drop falls the pins first make the holes for the insertion of the wire which is to be put through to form the bale-tie, and the punches at the next stroke cut out the head.

The relative position of the pin-receivin g holes and the openings for the punch is such that the pins cut theholes in the metal strip at the proper place for them to be in the head after this is struck out by the punch, such position of the holes being about the center of the triangle, or a little nearer the base.

As the face of the die wears, the table I can be lowered by means of slottedlugrand bolt L.

openings arranged side by side, the apex of one by the base ofthe other, and having, also, two holes out of line with each other, and each out of line with the center of one of the triangular openings, in combination with a reciprocating plunger provided with punches and pins corresponding in shape and position to the openings and holes in the die-plate, as set forth.

2. Table I, hinged at its end t, and having at its inner end, j, the dependent slotted lug r, in combination with bolt L, as set forth.

-In testimony whereof I aflix my signature in presence of two witnesses.
